Abstract

Frequent episodes of polymorphic ventricular tachycardias/ventricular fibrillation (VT/VF) in patients with coronary artery disease can be triggered by monomorphic ventricular premature beats (VPBs) and thus, amenable to catheter ablation. The goal of this study was to review single-center experience in catheter ablation of electrical storm caused by focally triggered polymorphic VT/VF. Catheter ablation of electrical storm due to focally triggered polymorphic VT/VF was performed in nine patients (mean age, 62+/-7 years; two females). All patients had previous myocardial infarction (interval of 3 days to 171 months). Mean left ventricular ejection fraction was 27+/-6 percent. All patients presented with repeated runs of polymorphic VT/VF triggered by monomorphic VPBs. Based on mapping data, the ectopic beats originated from scar border zone on interventricular septum (n=5), inferior wall (n=3), and lateral wall (n=1). Catheter ablation was performed to abolish the triggering ectopy and to modify the arrhythmogenic substrate by linear lesions within the infarct border zone. The ablation procedure was acutely successful in eight out of nine patients. During the follow-up of 13+/-7 months, two patients died due to progressive hear...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
